Cape Town - French Top 14 giants Toulon are aggressively recruiting some of the biggest names in world rugby as they bid to return to the top of the European ranks.
The latest player to be added to their squad is standout Argentina No 8, Facundo Isa.
Isa was widely regarded as the No 1 eighthman in the southern hemisphere last year, and at 23, bright things are expected from the burly Argentine.
Isa's move is a massive blow to the both Argentina and the Jaguares.
According to the Toulon website, Isa will join the club at the end of the season when his current contract with the Jaguares runs out.
Isa has signed a two-year contract.
What Isa's arrival means for the future of 30-year-old Toulon skipper and No 8, Duane Vermeulen, remains to be seen.
Isa, as a 20-year-old, played one match for Toulon in 2014, before returning to Argentina to play for the Pampas XV (in South Africa's Vodacom Cup), before switching to the Jaguares in 2016.
Isa will link up with new Toulon signings Chris Ashton, Raphael Lakafia, Semi Radradra, Hugo Bonneval and Filipo Nakosi next season.
In addition, on Thursday it was confirmed that former All Blacks great Ma'a Nonu had extended his stay at the club by a further year.
Toulon are currently fifth in the Top 14 standings, some 12 points adrift of leaders La Rochelle after 17 of the season's 26 matches.
